The antibody was purified by affinity chromatography and conjugated with PE under optimal conditions. The solution is free of unconjugated PE and unconjugated antibody.
Recommended Usage
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. Test size products are transitioning from 20 µl to 5 µl per test. Please check your vial or your CoA to find the suggested use of this reagent per million cells in 100 µl staining volume or per 100 µl of whole blood. It is recommended that the reagent be titrated for optimal performance for each application. Read more at www.biolegend.com/testsize regarding the test size change.

Description
TGF-β1 (transforming growth factor β1) is a multifunctional cytokine which regulates cellular proliferation and differentiation. It is ubiquitously expressed by many types of cells. Platelets express high level of TGF-β. TGF-β is synthesized as a large protein precursor and then secreted as a complex of TGF-β and LAP (latency-associated peptide), in which LAP noncovalently associates with the dimeric mature TGF-β to prevent its activity. TGF-β requires activation before it binds to its receptors and exerts functions. It has been reported that LAP-TGF-β binds to the integrins αvβ1, αvβ6, αvβ8, and α8β1 through RGD domain. TGF-β plays important roles in control proliferation and differentiation of epithelial cells, endothelial cells, fibroblasts, neurons, osteoclasts, and osteoblasts. TGF-β is believed to be important in the regulation of the development of Treg, Th17, and Th9 cells. A recent study has shown that LAP is an activated Treg surface marker.
